What is Kubernetes persistent volume?

A persistent volume is a piece of storage in a cluster that an administrator has provisioned. It is a resource in the cluster, just as a node is a cluster resource. A persistent volume is a volume plug-in that has a lifecycle independent of any individual pod that uses the persistent volume.

What is the difference between StatefulSet and deployment?

A StatefulSet is another Kubernetes controller that manages pods just like Deployments. But it differs from a Deployment in that it is more suited for stateful apps. A stateful application requires pods with a unique identity (for example, hostname). One pod should be able to reach other pods with well-defined names.

What is mountPath in Kubernetes?

The mountPath is the path of where the volume is accessible from within the container. In your first container, /go/src/github.com/username/reponame acts as a persistent directory. I'm guessing that / can't be mounted because it would overwrite all the contents of the pod (system files, etc.).
